Abstract

A geological study for the renewal of the geological map was conducted on the gabbroic massif of Ankerana. The objective was to identify all the geological formations constituting this massif, called gabbroic according to H Baiserie in the "Geology of Madagascar", in order to establish a detailed outcrop map of this area. The determination of the rocks was made from the macroscopic and microscopic petrographic description of the geological formations outcropped and sampled by grid of 500 meters. At each station, a detailed petrographic study, structural measurements crossed with the map of the lineaments realized on GIS, a geomorphological analysis were made. These are the essential elements for the establishment of the lithostructural mapping. The results allowed the identification of ten different rock types including Peridotite, Pyroxenolite, Amphibolite, Gabbros, Dolerite, Milky Quartz Vein, Leptynite, Ferruginous Cuirasses, Iron Oxide grains, Bauxitic Carapaces and red and yellow soils The new lithostructural map verifies the presence of ultrabasic formations that are alternated with basic rocks and/or residual rocks. This set has been intersected by quartz veins that are obtained after circulation of the last magmatic liquids inside the weaknesses zones where they crystallize
